Description

Technical Field

[0001] The utility model relates to the technical field of pipe expansion processing, in particular to an adjustable supporting pipe ejector for a lathe. Background Art

[0002] Pipe fittings are widely used in daily industrial production and life. Due to the error in pipe fitting production or the deformation of pipe fittings during transportation, in order to facilitate the connection of pipe fittings during assembly, it is necessary to deburr the end face of the pipe fitting and expand the hole at the pipe mouth. For large pipe fittings (ship stern tubes), burr treatment is generally performed on a lathe, while expanding the hole at the pipe mouth cannot be processed on a lathe. When the outer end of the pipe fitting is chucked on the lathe, the tool cannot enter from the outer end of the pipe fitting. Therefore, the pipe fitting needs to be removed from the lathe and then the pipe mouth is expanded by a boring machine, which makes the overall work efficiency low. Utility Model Content

[0003] In order to overcome the shortcomings of the background technology, the utility model provides an adjustable support pipe ejector for a lathe, which solves the problem that the hole expansion at the pipe mouth of a large pipe fitting cannot be processed on a lathe.

[0004] The technical solution adopted by the utility model is as follows:

[0006] The ejector rods are evenly distributed around the circumference of the ejector body, and the distance between the top surface of the ejector rods and the side wall of the ejector body is adjustable.

[0007] The bottom end of the ejector rod is provided with a threaded section, and the ejector pin body is provided with a threaded hole for cooperating with the threaded section.

[0008] The top surface of the push rod is in a spherical crown shape.

[0009] The top surface of the top rod is provided with an anti-slip layer.

[0010] The push rod comprises a head portion and a rod portion, and the cross section of the head portion is a regular polygon.

[0011] The four ejector rods are evenly distributed in the circumference of the ejector body.

[0012] The ejector rod is made of stainless steel.

[0013] The beneficial effects of the utility model are:

[0014] The ejector body is inserted into the inner hole of the pipe fitting, and then the length of the ejector rod is adjusted so that the ejector rod can support the hole wall. The ejector body can drive the pipe fitting to rotate, and finally the cutter head is applied to the pipe mouth of the pipe fitting to expand the hole. After the pipe fitting is deburred on a lathe, the utility model can expand the hole at the pipe mouth of the pipe fitting on the lathe, which can effectively improve the overall work efficiency.

[0016] Figure 2 This is the purpose of the ejector body of the utility model.

[0017] The ejector body 1 , the ejector rod 2 , the head 21 , the rod 22 , the threaded section 3 , and the threaded hole 4 . DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0019] In the embodiment, Figure 1 , Figure 2 As shown, an adjustable support tube type ejector for a lathe comprises an ejector body 1, and further comprises:

[0020] The ejector rods 2 are evenly distributed around the ejector body 1, and the distance between the top surface of the ejector rods 2 and the side wall of the ejector body 1 is adjustable.

[0021] The ejector body 1 is inserted into the inner hole of the pipe fitting, and then the length of the ejector rod 2 is adjusted so that the ejector rod 2 can support the hole wall. The ejector body 1 can drive the pipe fitting to rotate, and finally the cutter head is applied to the pipe mouth of the pipe fitting to expand the hole. After the pipe fitting is deburred on a lathe, the utility model can expand the hole at the pipe mouth of the pipe fitting on the lathe, which can effectively improve the overall work efficiency.

[0022] In the embodiment, Figure 1 , Figure 2 As shown, the bottom end of the ejector rod 2 is provided with a threaded section 3, and the ejector body 1 is provided with a threaded hole 4 for cooperating with the threaded section 3. By rotating the ejector rod 2, the distance from the top surface of the ejector rod 2 to the side wall of the ejector body 1 can be adjusted, and the adjustment is convenient.

[0023] In the embodiment, Figure 1 As shown, the top surface of the push rod 2 is in a spherical cap shape, which can better contact with the wall of the pipe hole and facilitate supporting the inner hole of the pipe.

[0024] In the embodiment, Figure 1 As shown, the top surface of the push rod 2 is provided with an anti-skid layer 5. The anti-skid layer 5 is a rubber layer or a silicone layer. When the push rod 2 is against the wall of the pipe hole, the anti-skid layer 5 prevents the pipe and the push rod 2 from sliding relative to each other, which affects the expansion quality at the pipe mouth.

[0025] In the embodiment, Figure 1 As shown, the push rod 2 includes a head 21 and a rod 22, and the cross section of the head 21 is a regular polygon. A wrench can cooperate with the head 21 to facilitate the height adjustment of the push rod 2.

[0026] In the embodiment, the four ejector rods 2 are evenly distributed in the circumference of the ejector body 1. After the four ejector rods 2 support the hole wall of the pipe fitting, the pipe fitting rotates stably along with the ejector body 1.

[0027] In the embodiment, the push rod 2 is made of stainless steel, which has good support strength, is not easy to rust, and has a long service life.

[0028] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to provide all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
